  • A case study "Value stream analysis of a re-engineered construction supply chain" is presented that documents the most common configuration of the supply chain for pipe supports used in power plants in the USA. This supply chain, like many others in construction, has numerous inefficiencies, many of which occur at the interfaces between processes, disciplines or organizations. Recognizing and understanding such inefficiencies, their causes and potential remedies provides a basis for process re-engineering.

  • This study aims to examine the charging current of a solar energy hybrid generator with a Genset / Diesel and the time used to fill the accumulator in conditions without load and load conditions. The results showed that the solar energy hybrid generator and Genset / Diesel prototypes were able to produce electrical power at 08.00 - 17.00 in the average sunny weather of 290.7 Wp without loading and at the time of load of 236.4 Wp. At night, the energy stored in the battery is converted into electrical energy to supply the load. Thus it can save electrical energy.

  • The Government of Kenya introduced energy sector reforms in the late 1990s aimed at improving efficiency in the supply of energy. After over two decades of reforms, there has been no comprehensive study to estimate the technical efficiency amongst electricity generators in Kenya. This study examined 27 thermal electricity generating plants in Kenya using data sourced from Energy Regulation Commission for the period July 2015 to December 2017. The study applied two methods to estimate efficiency, viz., the Stochastic Frontier Analysis and Data Envelope Analysis.

  • Renewable energy has become a promising way to meet growing energy needs in the society. However, operation of power supply systems based on renewable energy sources (RES) depends on a number of uncontrolled factors. This imposes certain restrictions on applications and causes applicationrelated challenges. At this point, the search for the best combination of applied energy sources has been still a key issue. Methodological approaches to the solution to this problem are diverse.

  • The newest waste management technology is bioconversion using fly larvae converting organic waste to insect larval biomass and organic residue. Bioconversion is a practice of recovering resources while simultaneously limiting the amount of organic material affecting landfill behaviour. Several organisms have been used in this treatment process. Several studies have been done using the black soldier fly larvae to degrade organic material.

  • This paper presents a third order continuous time current mode RD modulator for WLAN 802.11b standard applications. The proposed circuit utilized feedback architecture with scaled and optimized DAC coefficients. At circuit level, we propose a modified cascade current mirror integrator with reduced input impedance which results in more bandwidth and linearity and hence improves the dynamic range. Also, a very fast and precise novel dynamic latch based current comparator is introduced with low power consumption.

  • One of the most recent optimization techniques applied to the optimal design of photovoltaic system to supply an isolated load demand is the Artificial Bee Colony Algorithm (ABC). The proposed methodology is applied to optimize the cost of the PV system including photovoltaic, a battery bank, a battery charger controller, and inverter. Two objective functions are proposed: the first one is the PV module output power which is to be maximized and the second one is the life cycle cost (LCC) which is to be minimized.

  • This paper presents preliminary results of actual measured and simulated performances of a first year 806.52 kWp grid connected photovoltaic power plant located at Assa, southern Morocco (28.63°N - 9.47°W). The PV system consists of 8 AICHI on-grid PV inverters, 100 kVA each and 3432 SHARP Brand 235 kWp modules. The plant is divided into two groups of 4 inverters, each inverter is supplied by a PV field consisting of 33 strings of 13 seriesconnected modules facing south at a fixed tilt of 20°.The data presented in this study were monitored during the first year of operation of the plant.

  • The model of supply and demand is the economics profession’s greatest contribution to human understanding because it explains the operation of the markets on which we depend for nearly everything that we eat, drink, or consume. The model is so powerful and so widely used that to many people it is economics. This chapter explains how the model works and how it can explain both the quantities that are bought and sold in markets as well as the prices at which they trade.

  • This is a simple unipolar stepper board that can control stepper motors rated to 30VDC. The FET drivers are rated at 50A, but in practicality this board should not be used with motors anywhere near that current for several reasons. The power supply voltage, heat sinks and cooling used for the FET’s of your own application play an extremely important part in making that determination. The FET package is designed for 50 Watts of dissipative power. If you’re not wise in electronics, the board should be built in stages and tested during each stage to eliminate problems....

  • Another alternative often considered for power augmentation and/or to simply minimize the impact of ambient temperature effects is the use of inlet air chillers. Depending upon power plant economics—in conjunction with ambient temperature and plant load profiles—chillers can afford substantial economic value. This alternative cools the incoming air, thus increasing the output relative to the gain available with an evaporative cooler.
